Question

The number of hydrogen atoms in 6NH3 is

Answer 1

No 6 is common for N and H. 3 is only for H(Hydrogen).

For finding the number of hydrogen atoms we should multiply 6 with 3

So, 6*3 = 18. So there will be 18 hydrogen atoms in 6NH₃

Answer 2

Answer: 18

Step-by-step explanation:

This molecule, called ammonia, is a group of atoms held together by chemical bonds. In this example, the atoms (smallest pieces of matter) are nitrogen (N) and hydrgoen (H)

The number 6 indicates the number of moles of the NH3 molecule. A mole is the unit of measurement used to measure the number of atoms or molecules. One mole is equal to 6.02214078×10^23 of the same things.

And since there are 3 Hydrogen atoms found in each mole of ammonia, and there are 6 moles of amminia, then 6 x 3 = 18 atoms of hydrogen.
